The product has an interesting second appearance I'd say.
At first I simply wanted to write my thoughts while browsing multiple topics across different browser tabs and felt the need to quickly see my thoughts separated across various topics but, at once. I then felt a need to compare a paragraph that I wrote on one screen - the needs slowly expanded and escalated.
When I designed and coded the product first and showed it to my friends - all of them said that they wouldn't use it at first but they pinged not much later the day that they're starting to feel a need to use it and can see why I built it.
Nonetheless it's just a stupidly simple piece of web app made for fun.
Feel free to try it for the second time. :)
